PAPER-MAKING MACHINE.

To all wiwm it may concern:

Be ,it known that I, WILLIAM SHEAIIAN, a citizen of the United States,and a resident of the city of Ocean Falls, Province 5 of- BritishColumbia, Dominion of Canada,

have invented a certain new and useful Improvement in Paper-MakingMachines, of which the following is a specification.

This invention relates to the process of manuiacturing paper bymachines. As well known, such machines comprise press-rolls, by whichthe water is pressed out of theweb of paper, and drier rolls or driers;and the web has to be carried to said press-rolls and from these to thedriers.

Heretofore, it required a skilled attendant at each of the rose rollswhose duty it was to guide the ead' end of thewebof paper by hand, tosaid rolls. Such work involved some danger to theattendant, alsoinvolved loss of time, and waste of paper;

The web of paper being moist, the leading. end has a tendency to clingto one of the rolls between which it passes, if there are no guidingmeans.

The object of my invention is to rovide mechanical means by which thesaid lead end of the web is ided to and thru the press rolls to thedrlers.

I attain my object by means of compan on ropes or carriers travelling incontact w1th each other, and extending to and between the rolls, overand between which the lead end of the web of paper is to be guided.

5 At the receiving end of the first set of press rolls, these carriersare spaced apart so as to facilitate the insertion between of said leadend of the web, and a little farther on the carriers are brought intocontact jwith each other, so as to grasp and hold the lead end, and inthat wayfcarry and. guide the same thru the press rolls to the driers.

Other uses and v-applications of my invention will suggest-"themselves.I 7

ing drawings, I have diagrammatically ilustrated the practicalapplication of; my invention, the figures,

, showing as follows:

. I 2 re resent-endsections of a Figs: 1 and paper making mac ine, theviews showing two sets. of press-roll, and one of the drier, v i end a srolls; and

\ end of the web being "usually" torn .na1l across.

Fig. 3 is a fragmenta dia mmatic view of those ends of the gress r dllsadjacent the ropes or carriers, the upper roll being shown in sectionand the lower in side elevation; and this view shows the means providedon the projecting end of the upper roll for guiding the carriers pastthese press rolls, and so as to cause the, carriers to travel at thesame rate asgthe web of paper.

In describing1 the devices shown in the drawings, I wi refer only tothose parts which deal directly with my invention. The views shownrepresent parts of a machine of standard construction, therefore wellknown to all conversant with the paper making art.

a and I) represent one set of press rolls, and 0, 0! represent anotherset of press, rolls, it being understood that the machine may have anynumber .of sets of press rolls. The line e represents the felt runningthru the machine. f and g are the two endless ropes or carriers by whichthe lead end of the web of paper,. designated by the broken line g inFig. 1, is conducted to and between the press rolls, and finally to themeans, such as ropes h, for example, by which the web of aper isconducted to the drier rolls.

t the receiving end of the machine shown in Fi 1 the carriers f and 9run over sheaves i an i, which are arranged to guide the carriers sideby side along one edge of the web of paper, but these sheaves arevertically spaced apart so as to separate the receiving ends of thecarriers and permitthe placing of the web of pafiper between them, asdia ammatically i ustrated by broken ine fiin Fig. 1. A'short dlstancebe 0nd the s eaves 2' and j is provided anot er sheave 1-, forsupporting the carriers f and g the latter converging to that point, inso doing gripping and holding the lead end of the web of paper, andulling and guiding the -same thru the rst set of press rollsa and b.

In order toguide the web'of paper towards the press rolls it is onlynecessary to seize and hold one ed'ge' 'thereof this diago- T 6 upper1press roll a is'provided atone eave eIement consisting of a the wflanged guide ring 3 seated on ball bearings z mounted'on said end a'sshown in Fig. 3. Thetlanged ring 3 serves as a guidefor the carriers fand g as illustrated in Fig. 3, since the strain on said carriers tendsto hold them against the upper roll a.

The carriers f and 9 pass from the first set of press rolls to thesecondset 0, and 0!, as illustrated in 2, running over sheaves s, t, u,to said second set of press rolls, the upper c of which is also providedwith guiding means for the carriers like those shown in Fig. 3. Themeans provided on the upper of the press 'rollsforguiding the-carriersmustbe adapted to cause the latter to travel at the same speed as thatat which the web of paper is traveling. I

From the second press rolls 0, d, the carriers pass over sheave w to thedrier roll m,

at which point the carriers are carried over a pair of sheaves 3, whichare arranged to separate the carriers laterally so as to release thelead end of the web of paper. The lead end of the web of paper havingarrived at the drier roll w is then seized by the other guide ropes orcarriers h by which the lead end is carried over the drier roll as andthe drier roll 00'.

It" shows another of the carrierscarrying the leadend of the web ofpaper over the drier rolls. The latter carriers are arrangedsubstantially as shown in my Letters Patent of the United Statesreissued June 8, 1915,

No, 13,925, entitled Improvement in drier rolls for paper makingmachines.

'From the sheave 3 the carriers f and 'g' peass over the sheave p, whichis assumed to driven by being connected thru the medium of a clutch witha suitable driving "mechanism all of which details are readilyunderstood and therefore are not described. A The carriers run overthesheave p to the "sheave 0, thence over ti htening devices such as shownby m, a tin ig. 1; and from the sheave Z' of the latter devices thecarriers run over sheave 70 back to the sheavesi and y. When the lead"end of the web of paper has iteachedthe drier fioll m the driving ofthe sheave 'pjswhich drives the carriersmay be discontinued by throwingout the clutch of the sheave p until the carriers f and g are againrequired-to be thrown into action.
